Buying Computer Books in Barcelona

We went to about five bookstores, each having a tiny english second consisting of Lord of the Rings, Mike Moore books, and Tom Clancy Novels.
Furthermore the books cost a ridiculous amount.
Upon searching the internet I found someone who suggested using Amazon.com for computer books… I’ll probably just end up waiting two weeks until we are in England.

Jenn and I are on a quest, to find English language computer books in Barcelona.
The problem: Apparently bookstores here niether stock english books or computer books.
